Clean Architecture in Flutter
A practical guide to implementing clean architecture in Flutter applications with Bloc state management.
Clean architecture helps us build maintainable and testable Flutter applications by separating concerns into distinct layers.
The Layers
- Presentation — Widgets, BLoCs, and UI logic
- Domain — Entities, use cases, and repository interfaces
- Data — Repository implementations, data sources, and models
Why It Matters
By keeping these layers separate, we can:
- Test each layer independently
- Swap implementations without affecting other layers
- Scale the codebase as the app grows
Getting Started
Start by defining your entities in the domain layer, then work outward toward the data and presentation layers.
